European flat oysters (Ostrea edulis) were common in the Adriatic Sea, and extensive reefs were reported until the early 1900s. Due to habitat disturbance and overexploitation, flat oysters are now scattered and only by-caught in fisheries. The large-scale project “Restoration activities of natural Oyster beds in the ADriatic Sea”. (2023-2026) is financed by the National Recovery and Resilience Plan (Next Generation EU) in the framework of the Marine Ecosystem Restoration project (MER). It aimed at restoring wild native oyster reefs in seven sites along the Italian Adriatic coast.

The project foresees the deployment of 7 ha of substrates and the release of adult oysters in cages to enable larval supply and recruitment settlement. Monitoring activities will be carried out throughout the project. Oysters’ release will take place in 2025 and 2026.

Start date of project planning: September 2022.

Start date of active restoration activities: September 2024.

Primary objective: Restore self-sustaining native oyster habitats.

Secondary objectives: Increasing the biodiversity value of the site and delivering ecosystem services (support to marine-coastal biodiversity, erosion mitigation, CO2 sequestration, improvement of water quality and biomass production services).

Project partner organisations:

  • Italian Institute for Environmental Protection and Research, ISPRA (leading the project definition and implementation),
  • Ministry of Environment and Energy Security (administration responsible for the project under Next Generation EU Fundings).
